I've recently started to document the dieselFoam dictionaries.

The idea is to write down each dictionary so that it's possible to do a copy/paste and get some sort of default settings for all the dictionaries.

Each entry will be clickable and will give either all the different options and an explanation of what they mean, or a short description of the model with hopefully a reference.

Its far from finished, but as I've been writing I realized that it might be good if I could get some feedback about the form so that I dont have to re-write everything in case its just...crap http://www.cfd-online.com/OpenFOAM_D...part/happy.gif

Anyways...
If you want to take a peek at it I'd really appreciate some feedback

Hello Niklas,
Just a newbie question (since I'm not an expert in chemistry):
In the chemistryProperties dictionary, the entry chemistrySolver has an option called EulerImplicit which basically should solve an implicit algebraic system, stated as:

(1+\delta t B c^n_j)c^{n+1}_i = c^n_i + \delta t(A c^n_a c^n_b)

Correct me if I'm wrong, but isn't this an explicit system with the only unknown c^{n+1}_i?

Nope, but I admit the name is a bit mis-leading.
It should really be semiImplicit,
the off-diagonal terms are treated explicitly, while the diagonal term is implicit.
